## DMX Channel Layouts

### 13-Channel Mode (PAR, Blinder, Lightbar)

Standard full-featured control:

| Channel | Function  | Range | Description                      |
| ------- | --------- | ----- | -------------------------------- |
| 1       | Reserved  | 0-255 | Future use / compatibility       |
| 2       | Reserved  | 0-255 | Future use / compatibility       |
| 3       | Reserved  | 0-255 | Future use / compatibility       |
| 4       | Reserved  | 0-255 | Future use / compatibility       |
| 5       | Red       | 0-255 | Red color intensity              |
| 6       | Green     | 0-255 | Green color intensity            |
| 7       | Blue      | 0-255 | Blue color intensity             |
| 8       | Intensity | 0-255 | Master dimmer                    |
| 9       | Strobe    | 0-255 | Strobe rate (0=off, 1-255=speed) |
| 10      | Reserved  | 0-255 | Future use                       |
| 11      | Reserved  | 0-255 | Future use                       |
| 12      | Reserved  | 0-255 | Future use                       |
| 13      | Reserved  | 0-255 | Future use                       |

<Note>
  Channels 1-4 and 10-13 are reserved for compatibility with the mover channel layout. Static lights only actively use channels 5-9.
</Note>

### 5-Channel Mode (PAR, Blinder, Lightbar)

Simplified control for basic fixtures:

| Channel | Function  | Range | Description                      |
| ------- | --------- | ----- | -------------------------------- |
| 1       | Red       | 0-255 | Red color intensity              |
| 2       | Green     | 0-255 | Green color intensity            |
| 3       | Blue      | 0-255 | Blue color intensity             |
| 4       | Intensity | 0-255 | Master dimmer                    |
| 5       | Strobe    | 0-255 | Strobe rate (0=off, 1-255=speed) |

<Note>
  5-channel mode is more efficient for simple setups where the extra reserved channels aren't needed.
</Note>

### 1-Channel Mode (Flasher)

Minimal single-channel control:

| Channel | Function  | Range | Description                 |
| ------- | --------- | ----- | --------------------------- |
| 1       | Intensity | 0-255 | Master dimmer / strobe rate |

### 15-Channel Mode (Multi-Lightbar)

Extended control for multi-segment lightbars:

| Channel | Function  | Range | Description                |
| ------- | --------- | ----- | -------------------------- |
| 1-4     | Reserved  | 0-255 | Compatibility              |

| 11      | Segment 2 | 0-255 | Individual segment control |
| 12      | Segment 3 | 0-255 | Individual segment control |
| 13      | Segment 4 | 0-255 | Individual segment control |
| 14      | Reserved  | 0-255 | Future use                 |

## Inspector Properties

### DMX Settings

```csharp theme={null}
enableDMXChannels     // Enable/disable DMX control
dmxChannel            // Starting DMX channel (1-512)
dmxUniverse           // DMX universe (1-9)
nineUniverseMode      // Extended universe mode
useLegacySectorMode   // Legacy sector addressing
singleChannelMode     // Enable 1-channel mode (Flasher)
```

### Fixture Settings

```csharp theme={null}
enableStrobe          // Enable strobe effects
coneWidth             // Beam width (0-5.5)
coneLength            // Beam length (0.5-10)
maxConeLength         // Volumetric mesh length (0.275-10)
tiltOffsetBlue        // Fixture aim angle (0-360°)
panOffsetBlueGreen    // Fixture rotation (0-360°)
```

### Intensity Settings

globalIntensity               // Master brightness (0-1)
finalIntensity                // Maximum brightness limit (0-1)

finalIntensityVolumetric      // Volumetric brightness (0-1)
finalIntensityProjection      // Projection brightness (0-1)
finalIntensityFixture         // Fixture mesh brightness (0-1)
```

### Color Settings

```csharp theme={null}
lightColorTint        // HDR color tint (default: white)
```

## Configuration Examples

### Basic PAR Light Setup

1. Place PAR light prefab in scene
2. Configure DMX settings:
   * DMX Channel: 1 (or 1, 6, 11, etc. for 5CH mode)
   * DMX Universe: 1
   * Enable DMX Channels: ✓
3. Adjust beam settings:
   * Cone Width: 3.0 (wider than spotlight)
   * Cone Length: 5.0
   * Tilt Offset: 90 (aim straight down)
4. Position and aim fixture as needed

### Flasher Array

For efficient flasher arrays:

```csharp theme={null}
enableDMXChannels = true
singleChannelMode = true
dmxChannel = 1, 2, 3, 4... (sequential)
enableStrobe = true
```

Place multiple flashers and assign sequential channels. Control all from a single DMX range.

### Lightbar Wash

For wide area coverage:

```csharp theme={null}
coneWidth = 5.0              // Maximum width
coneLength = 8.0             // Extended reach
tiltOffsetBlue = 45          // Angled for wall wash
finalIntensityVolumetric = 0.3  // Reduce cone visibility
```

### Blinder Effects

For high-intensity strobe effects:

```csharp theme={null}
enableStrobe = true
lightColorTint = Color.white * 3.0  // Boost intensity
finalIntensity = 1.0
globalIntensity = 1.0
coneWidth = 4.0              // Wide spread
```

## Aiming and Positioning

### Tilt Offset

Use `tiltOffsetBlue` to aim the fixture:

* 0° - Horizontal forward
* 90° - Straight down
* 180° - Horizontal backward
* 270° - Straight up

### Pan Offset

Use `panOffsetBlueGreen` to rotate the fixture:

* 0° - Forward
* 90° - Right
* 180° - Backward
* 270° - Left

### Combined Aiming

Combine both offsets for precise aiming:

```csharp theme={null}
tiltOffsetBlue = 45      // 45° down
panOffsetBlueGreen = 30  // 30° to the right
```

## Shaders

Static lights use the following shaders:

* `VRSL-StaticLight-ProjectionMesh.shader` - Light projection
* `VRSL-StaticLight-LensFlare.shader` - Fixture lens effect

**Location:** `Runtime/Shaders/StaticLights/`

Lightbar-specific shaders:

* `Runtime/Shaders/StaticLight-LightBarAndFlashers/`

## Use Cases

### PAR Lights

* **Stage Washes** - Color washing stages and sets
* **Uplighting** - Wall and backdrop illumination
* **Truss Lighting** - Mounted on trusses for overhead coverage
* **Floor Lighting** - Ground-mounted for uplighting effects

### Blinders

* **Audience Blinding** - High-intensity flash effects
* **Strobe Effects** - Synchronized strobing
* **Impact Moments** - Dramatic emphasis
* **Photo Flash** - Simulated camera flashes

### Flashers

* **Accent Lighting** - Simple on/off effects
* **Edge Lighting** - Truss and structure outlining
* **Strobe Arrays** - Large groups of synchronized strobes
* **Background Effects** - Ambient flashing

### Lightbars

* **Linear Washes** - Continuous line of light
* **DJ Booth Lighting** - Front-facing wash effects
* **Stage Edging** - Stage border illumination
* **Architectural Lighting** - Building facade lighting

## Performance Optimization

### Use 5-Channel Mode

When you don't need the full 13-channel layout:

```csharp theme={null}
// Use 5CH prefabs instead of 13CH
// Saves DMX address space and processing
```

### Disable Unused Features

```csharp theme={null}
enableStrobe = false         // If strobing not needed
finalIntensityVolumetric = 0 // Disable volumetrics if not visible
```

### Component Mode Optimization

```csharp theme={null}
finalIntensityComponentMode = true
finalIntensityVolumetric = 0.2    // Reduce volumetric
finalIntensityProjection = 1.0    // Keep projection
finalIntensityFixture = 0.5       // Reduce fixture mesh
```

## Troubleshooting

### Fixture Not Lighting

* Check DMX channel assignment
* Verify RGB channels (5-7 in 13CH, 1-3 in 5CH) have values
* Ensure intensity channel is above 0
* Check `enableDMXChannels` is enabled

### Wrong Colors

* Verify channel offset is correct
* Check universe assignment
* Ensure RGB channel order matches DMX software
* Test with manual color tint to verify fixture works

### Strobe Not Working

* Verify `enableStrobe` is enabled
* Check strobe channel (9 in 13CH, 5 in 5CH) has value
* Ensure strobe value is above threshold (\~20)
* Verify VRSL Grid Reader strobe output is enabled

### Flasher Too Dim

* Increase `lightColorTint` intensity (HDR value)
* Boost `globalIntensity` to 1.0
* Set `finalIntensity` to 1.0
* Check single channel mode is enabled correctly

### Beam Not Visible

* Increase `coneLength` and `coneWidth`
* Boost `finalIntensityVolumetric`
* Ensure post-processing bloom is enabled
* Check fixture isn't obscured by geometry

## AudioLink Integration

AudioLink variants support:

* Band selection for intensity modulation
* Band multiplier for sensitivity
* Color chord sampling
* Theme color integration
* Per-fixture delay offset

See [AudioLink Setup](/guides/audiolink-setup) for configuration details.
